(CNN) -- An 11-year-old baby sitter in suburban Atlanta, Georgia, has been charged in the death of a 2-year-old, authorities said.

The baby sitter is accused of felony murder and cruelty to children, according to Lt. Steve Rose, spokesman for the Sandy Springs Police Department.

The baby sitter, who is a daughter of a co-worker of the victim's mother, was caring for Zyda White late Saturday. The mother of the 2-year-old called 911 from the baby sitter's home after returning to pick up her child, police said.

Zyda was taken to Scottish Rite Hospital, where she was pronounced dead, Rose said in a statement. An autopsy indicated she suffered blunt-force trauma to her head, torso and buttocks, CNN affiliate WSB reported.

Zyda's mother, Ashlea Collier, told CNN affiliate WSB her daughter's eyes were wide open when she got there. The baby sitter's mother started CPR. The 11-year-old told her that Zyda had fallen out of bed, that she put her back and gave her apple juice, Collier said.

Sandy Springs police are conducting interviews and examining evidence from the autopsy.

The 11-year-old was taken Tuesday to the Metro Youth Detention Center in Fulton County.

It was unclear whether the case will be handled by juvenile authorities.
